I need set jumbo frames on some ports (SAN for VMware an Dell Equallogic) only L2. After some searching i set "system mtu 9000". Everything ok on SAN network but i ger error "Process 1, Nbr 192.168.168.1 on Vlan303 from EXSTART to DOWN, Neighbor Down: Too many retransmissions". It looks as problem with mtu size of ospf. So question is how set mtu 9000 for L2 and 1500 for L3 globally or better solution?
